Good call by whoever thought this up though, sounds like deeper integration than a PR agency could usually come up with. Bit controversial viewpoint - hope someone can prove me wrong!
Interesting though - Sony were reasonably careful to make the PS2 quite separate from a PC. This development shows that it will be able to load some third party programmes which will not necessarily be games. Since the PS3 is being sold at a subsidised price, will we see it expand into new functions? OpenOffice for the PS3 - they've already fitted it with a USB port so a keyboard shouldn't be too difficult.
